Maintenance and use: Electrical insulating gloves are generally soft and easily damaged by mechanical elements. Leather outer gloves are to be worn over electrical insulating gloves to provide a means of mechanical protection. To maintain electrical insulating gloves in a reliable working condition, perform an air test and visually inspect them for damage before each use and immediately following any incident where it is reasonable to suspect damage.
Electrical insulating gloves are to be tested before first being issued for service and every 6 months afterwards. They are not to be placed in service unless they been electrically tested within the preceding 12 months
